Use the Compression tab to change the block size and remove variable length record (VLR) metadata from LAS files.
The block size is the number of points that GeoExpress processes and stores at one time. Enter a large block size to increase compression speed. Enter a small block size to decrease memory usage. Valid values are from 2048 to 16384. The default value is 4096.
If you select the Omit Custom LAS VLR metadata option, GeoExpress removes VLR metadata from LAS files. VLR metadata can include vendor-specific data, user-specified data, and more.
